Hi, This is my first year in business and I've noticed how much competition there is when you only mow, or do basic landscaping. Also the labor is easier with this side of the business, as well there is less competition and better profit margins. So, before next season begins I want to be licensed to apply weed control and fertilization chemicals. How do I do this in Kentucky? How much does it cost? Do I take classes? If so how long? And do you think this is a good idea for my business? Thanks any and all.
